[o all whom t 'may concern: 1

Be it known that l, "Washer iiguiroNs, a citizen ot' the United. States, residingl at Cleveland,v in the countyot- Cuyahoga and State et Ohio, have invented a certain new and useful lmproven'ient in Vl-tadiatoi's, ot which the following is a full, clear, and 'exact descrijjition, reference boing had to the acconipanying,` drawings.

This invention relates to fluid heaters. and more 'particularly to heaters olI the radiator type, wherein heat is delivered to the 'air within a room or similar space by radiation and convection.

It is the general object of the invention to increase the efficiency oit such heaters in the matter of the interchange ot' heat units between the fluid circulated through the radiators and the fluid which is to be heated thereby. A further object of the invention is to provide such devices with improved means for moistening the air which is heated thereby. I accomplish these objects in and through the constructions shown in the drawing forming a part hereof, wherein Fig. l represents a iront elevation ot' a radiator constructed in accordance with my invenn tion, the said radiator being ot' the type used for the heating ot rooms or compartments by means of water-vapor or steam, some oilithe heat-interchanging tubes being omitted; Figs. 2 and 3 are sectional details corresponding respectively to the lines 2 2 and 3-3 ot Fig. l; Fig. 4 is a view, similar to Fig. l, of a radiator embodying` my invention and which is particularly adapted ttor use with hot air registers; andFig. 5 is a sectional view correspondingto the line 5-5 of Fig. 4.

Describing the various parts herein by reference characters, l denotes the upper header and 2 the lower header of a radiator of the ordinary house-heating type, the radiator being shown as supported on brackets 3 secured in any suitable manner to a. wall l-it being understood that, so far as my invention is concerned, the particular means ltor supporting the radiator is immaterial,

The upper header l is provided with a supply pipe 5 and the lower header with the return pipe 6, as is usual in radiator construction.

The headers are connected by means of ducts 7 corresponding to the loops ordinarily employed, the depth of each duct be- Serial No. 589,302.

ing substantially equal to the depth ot' the headers and the width, as viewed from the iront, being' considerably narrower than the depth. In practice, the ducts or loops may be about 1/2 in width. The endsot the 60 radiator may be formed either by ducts or loops 7 or by end plates 8 as shown).

ldith the parts constructed and arranged as thus :tar described, the radiator will operate in the ordinary manner, the plates 8 65 being heated by radiation from the adjacent loops and delivering their heat `by radiation and convection to the air in the vicinity thereof and passing in contact therewith. i

F or the purpose of increasing the heating effect of the radiator, I interposc between adjacent chiots or loops (as well as between each end duct or loop and the plate 8 adjacent thereto) a plurality of heat-conducing and radiating tubes. These tubes 9 are 75 preferably hexagonal in shape, which will enable them to be assembled between the adjacent ducts or between the ducts and the plates adjacent thereto in the manner shown that is to say, with pairs of horizontally arranged tubes alternating with single tubes, the hexagonal shape of the tubes enabling each tube oi each pair to engagea duct or plate with one side and the other tube with its opposite side, while the intermediate singjle tube fits within the angles I:termed between the bottoms of an upper and the tops of a lower pair of such tubes. Furthermore. while the tubes are substantially horizontal, they are slightly inclined from front to 9o rear, as will appear from 3, to facilitate the circulation of heated air therethrough.

An extremely convenient manner of forming the radiator is to make the ducts or loops 7 half the width of the space between 95 adjacent ducts or loops while the tubes are of the same diameter as the width of said ducts or loops. This will enable the tubes to be conveniently nested between adjacent ducts or loops and between the end ducts 10o or loops and their adjacent end plates 8. The construction described enables the loops or ducts to deliver their heat by conduction and radiation to the tubes 9 while the latter will deliver their heat by radiation and convection to the air passing therethrough and adjacent thereto.

The header l is provided with an airmoistening trough 10, which may be conveniently pressed from the metaLof said U0 header, sheet metal being preferably employed for the material of the radiator. This trough is provided with a faucet 1l whereby water from the system may be introduced into the trough, (should the system be a water-heatii'ig system) while the top is provided with a removable cover l2 provided with perforations not shown) for the escape of water vapor into the atmosphere.

In Figs. 4L and 5 there is shown a modification of the invention, Whereinthe upper header 13 is substai'itially identical with the header l except that it is not provided with a suppl)7 pipe but, instead. is provided with apertures 14, on each side of the air-1noistening trough l0, to permit of the escape of air into the room or compartment in which the radiator is located. The lower header l5 is also devoid of any pipe but is open at its bottom and is provided with louvers 16. This radiator is adapted to receive hot air from a furnace and to circulate the same, when the louvers 16 are open, through the ducts or loops 7 and the upper header. The tubes 9 will operate as before in increasing the efficiency of the headers and loops or ducts.

The whole construction may be made cheaply and conveniently of sheet metal and is extremely efficient in utilizing the heating- Huid to the best advantage and in circulating the air in operative relation to the radiator elements. Forthe sheet metal. lY prefer aluminum or copper, because of their great heat-radiating' qualities and immunity from rust or oxidation; but I may also us alloys of copper, such as bronze or brass. i

Having thus described my invention, what l claim is:

l. A radiator comprising an upper and a lower header and intermediate ducts connecting the same, tubular elements of conductive material interposed between adjacent ducts and having thermal contact there* with and with one, another', said tubular elements being inclined to the horizontal to facilitate the circulation of air therethrough and therebetween, a trough formed within said upper header and wholly enclosed thereby and a valved connection between said trough and the interior of said upper header.

2, A radiator comprising an upper and a lower header and intermediate ducts connecting the same, the top of said upper header having' a downwardly extending p0rtion adapted to form a U shaped troligh, lying' wholly within the contour of said upper header, a perforated cover for said trough and a valved conduit for communieating' said trough with the interior of said upper header.

8. A radiator comprisingf in combination an upper and a lower header and ducts coni'iecting; the same` the said upper header hava trough formed therein and lying wholly within the contour of said upper header and a removable perforated cover for said trough` means for lillingsaid trough from ihe liquid in said radiator, said means lying wholly within said upper header and accessible only when said cover is removed.

In testimony whereof, I hereunto affix my signature.
